Nano Coated Steel

Nano coated steel is a new type of building material for high temperature and high corrosion applications. Nano coating has excellent resistance to heat, corrosion, fire, acid, and alkali. At the same time, it also has great performance in noise reduction, energy saving, and environmental protection. Due to its advantages, it is considered an ideal roofing and exterior wall material, which is widely used in civil buildings, granaries, steel mills, power plants, chemicals, breeding, and other fields.

What Is Nano Coated Steel?

Nano coated steel is a composite metal sheet, using galvanized steel, or color coated steel, or aluminum sheet, as base metal. And then the substrate is covered with a nanomaterial layer, including anti-aging adhesive, spectral reflection aluminum foil, and anti-aging PET film (as shown in the picture below). Nano anti-corrosion material refers to materials with a size between 0.1-100nm. It is applied on the surface of base metal to achieve the effect of heat insulation and corrosion resistance.

Advantages of Nano Coated Steel

1. Strong anti-pollution & anti-static capacity

The surface of the nano coated steel is very dense and smooth. Besides, it is able to eliminate the electrostatic effect so it is very difficult for dust, oil fume, and other dirt to be adsorbed on its surface. Moreover, it is easy to clean.

2. Super wear resistance

The wear resistance of the nano coated steel is 10+ times stronger than that of ordinary coatings, so it is not easy to leave scratches.

3. Excellent thermal insulation performance

Nano coated steel is of higher light reflectivity and lower thermal conductivity than other materials. Due to spectral reflection film, 70%-80% of visible light with wavelengths of 0.38-0.765m can be reflected, and 75-100% of infrared light with wavelengths of 0.76-505 m can be reflected. The reflection coefficient is higher than 80%, which means more than 80% of heat can be scattered, and only a tiny part can be absorbed. Moreover, the thermal conductivity of nano coated steel is 2.93W/m.k., while that of common color coated steel is 40W/m.k. So the surface temperature of nano coated roofing can drop by 10-15℃ in summer, and the indoor temperature will be 5-10℃ lower.

4. Long service life

Nano coated steel has excellent acid and alkali resistance, weather resistance, fire resistance, and corrosion resistance. Its design life is more than 15 years. It can be guaranteed for 10 years even in corrosive environments such as acid corrosion, high/low temperature, etc. That’s why it is widely used as roofing and exterior wall materials.

Different Colors


1. Various steel plants and foundries. Anti-corrosion sheet is not easy to rust or leak and can be guaranteed for 10 years even in corrosion, high temperature, high humidity, and other environments.

2. Cold storage roofing and wall system. Nano steel sheet has a better thermal insulation effect, which is a new building material for energy saving and emission reduction for cold storage.

3. Steel structures. Nano coated steel is light in weight which can reduce the load-bearing requirements of the steel structure. So it is easy to install to shorten the construction period and save the project cost.

4. Chemical plants. Nano anti-corrosion steel has excellent acid and alkali resistance, and solvent resistance, which makes it suitable for chemical plants.

5. Husbandry farms. Excrement and feed are easy to produce hydrogen in hot and humid environments to corrode the roofs. And the high temperature affects the growth of livestock, breeds bacteria, and creates great operational risk. The anti-corrosion sheet is an ideal material for farm buildings.

6. Workshops requiring constant temperature and humidity. Like workshops for electronics, medical, food, etc., there are high requirements for thermal insulation. Nano insulated steel sheets can lower the indoor temperature by 5-10℃.

Applications of Anti-corrosion Steel

Applications of Nano Anti-corrosion Steel


Q: Can nano steel be bent? Can it be profiled?

A: The substrate of the nano coated steel is still galvanized steel sheet or other metal. Nano coating is only a kind of surface treatment method. The original metal properties have not changed. So it can be bent, profiled, cut, etc. However,  its anti-corrosion and heat insulation properties are much better than that of color coated steel.

Q: Is nano anti-corrosion insulation sheet suitable for outdoor use?

A: Definitely yes. The nano coated steel has excellent corrosion resistance, acid and alkali resistance, and heat insulation. So it is applicable to many harsh environments with high temperature, high humidity, and high corrosion.

Common Color Coated Steel VS Nano Coated Steel

1. Heat Insulation

Experiments show that when the outdoor temperature is 36 °C, the surface temperature of ordinary color steel can reach 63 °C and the indoor temperature is about 41 °C. While the surface temperature of nano heat insulation sheet is about 40 °C and the indoor temperature is about 33.5 °C. Because the spectral reflective film can reflect 85% of the ultraviolet rays, both outdoor and indoor temperatures of the nano thermal insulation board are much lower.

2. Corrosion Resistance

Put the common color steel sheet and the nano anti-corrosion sheet into 98% sulfuric acid. The color the former painting changed instantly and paint film fell off five minutes later. While the anti-aging protective film on the surface of the nano anti-corrosion sheet is intact. Nano steel has super acid, alkali, and corrosion resistance. It is suitable for chemical plants, ceramic plants, smelters, foundries, and other harsh use environments.

3. Price

Nano-coated steel is more expensive than common color coated steel. But it is more durable and its service life is more than 10 years even under harsh use environments. In the long run, it is more cost-effective.


Nano heat insulation sheet is a new kind of material. It is available in different materials (such as galvanized steel, aluminum sheet, etc.), different colors, specifications, and surfaces. The commonly used colors include silver white, sea blue, gray, red, camouflage, and so on. You can choose according to your preference. It has the advantages of great weather resistance, acid and alkali resistance, corrosion resistance, heat insulation, sound insulation, and fire protection. That’s why it is getting popular. Moreover, it is easy to process to meet the needs of different applications. Therefore, it is promising to invest in. Wanzhi Steel is a factory to offer various metal products at a competitive price.
